' To all whom it may cone em:

' Be it knownthat I, J AMEs'I-LBoYE, a citizen of the United States,residing at Chicage, in the county ofCook and State of Illinois, haveinvented a new and useful Improvement in Faucets, of which the followingis a specification. t

My invention relates to faucets adapted to supply either hot or coldwater, or any desired iiiixture thereof. a

My primary object is to provide afaucet of improved construction. andoperation, whichwill enableeither hot or cold water to besecur'ed inadequate volume, and any desiredmixture of hot and cold water to besecured by the operation of a single actua ting device. a The inventionis adapted-for use, among other purposes, in connection with bath-tubs,wash-bowls, sinks, etc. Y

My invention is illustrated in its pre ferred embodiment in theaccompanying drawing, in which Figure 1 represents a plan view of afancet constructed in accordance with my inventionaFig. 2, a brokenvertical section taken as indicated at line 2 of F 1, this View showingthe valves controlling th e'hot and cold water conduits closed; Fig. 3,a broken plan section taken approximately as indicated at line 4 of Fig.2, with the valveunseating cams in the position shown in Figs. '1 and.2; Fig. 4, ,a section taken as 1ndicated at line 4 of Fig. 2, butshowing the cams-in-such'position as to wholly unseat the valvecontrolling the cold water admission, while the valve for controllingthe hot water. admission remains seated; Fig. 5,- a similar sectionshowing the cold-'water-controlling valve seated'and the hot-watercontrolling valve unseat-ed; and Fig. v6, a broken section taken asindicated at line 6 of Fig. 2,;and showing a stopedevice for limitingthe oscillating movements'of the rotary shaft which carries thevalve-unseating cams.

In the construction illustrated, A represents a casing or mixingchamber; B, a hot water conduit connected with the cylindrical wall ofthe casing; B a cold water conduitconnected' with the cylindrical wallof the casing at a point diametrically opposite; C, a discharge-spoutconnected with the cylindrical Wall of the casing at a oint midwaybetween the points of communication of the supply-conduits; and D, valveunseating 12.01 crtlcaeo, LL NoIs, assreuon T0 JOHN L.

mechan'ism. The casing preferably com-.

'tuting a cylindrical wall 2; and a removable front or top plate ,3,"which mayhave threaded connection ,with the wall 2, as

shown in Fig. 2.

The inlet-conduits B and B 'are preferably located in different planes.At their points of communication with the mixingchamber, they areprovided with valve-seats 1 contacted byinwardly-seating ball-valves2flwhich project somewhat within the mixing-chamber. in the form ofpipes equipped with'reinov-' able end-plugs 3. The branch pipe, ornipple, 4 communicates with the conduit B; ,and a branch-pipe, ornipple, 5 communicates with the conduit B Connection may be made withthe watersupply pipes of a building through said nipples.

cams 9 and 10 fixedly mounted on the' 'shaft The conduits B and B are"The valve-unseating mechanism D- com-, "prises a shaft 6 which extendsthrough'the within the chamber A. The cam. 9 is lo-' cated in the sameplane as the valve controlling the conduit B; and the cam 10 is locatedin the same plane as the valve controlling the conduit B lar relation toeach other. Thatis fto say,

1 the lowest point of the low portion 9 of the cam 9 is approximately180 fromthe lowest'point of the low portion 10 of the cam 10 andconsequently the recess 9 of the cam 9' is "approximately (although notquite) 180 from the recess 10 of the cam 10.

- The disk, or plate, 3 serves as an index or dial over which thepointer 8 plays. Thus, the upper or outer surface of the plate 3 ismarked at its rear portion with the word Ofi' which indicates, when thepointer is turned to that point, that both the hot and cold water areshut off and the front portion of the outer surface of the plate 3 ismarked with the words Hot and Cold, spaced a short distance apart,

u The cams are shown as eccentrically mounted disks having the low' andindicating, when the pointer is turned.

- to one. or the other, all hot or all cold water,

as the case may be.

In Fig. 6, the lower portion of the shaft 6 is shown equipped with astud 11, which is adapted to engage a stud, or stop, 12, which projectsupwardly from the lower wall 1 of the mixing chamber. The full-lineposition of the stud 11 corresponds with the position of the cams whenthe pointer 8 points to the word Cold in Fig. 1; and the dotted lineposition of the stud 11 corresponds with the position of the cams whenthe pointer points to the word Hot in Fig. 1. The stop for limiting therotation of the shaft 6 may or may not be. employed, according todesire. When the pointer is in the position shown in Fig. 1, the lowpoints 9 and 10 of the cans are adjacent the hot-water-controlling valveand the cold-water-controlling valve, respectively, but not in contacttherewith; Rotation of the shaft in one direction will give a mix tureof hot and cold water, that is tepid water, .and will then give, whenthe pointer reaches the cold-index position, an entirely cold supply.When the shaft is rotated from the closed position in the oppositedirection, a mixture will first be given, and then, when the pointerpoints to the hot-index point, an entirely hot supply will be obtained.

From the foregoing description, it will be understood that it ispossible, with my improved construction, to secure an abundant supply ofeither hot water or cold water, or to secure any desired mixture, byactuating a, single valve actuating device.

While the use of similar cams and the described arrangement arepreferred, the invention is not limited thereto; nor is it essentialthat the cams should be separatelyformed.

The foregoing detailed description has been given for clearness ofunderstanding only, and no undue limitation should be understoodtherefrom, but the appended claims should be construed as broadly aspermissible in view of the prior art.

'said ball valves, and means for What I regard as new, and desire tosecure by Letters Patent, is-

1. A device oi the character set forth. comprising a mixing-chamberequippe with an outlet-passage and equipped with inlet-conduits,inwardly-seating valves in said conduits projecting into saidmixingchamber, a shaft extending into said 'mixing-chamber and equippedwith valve actuating means comprising a pair of similar cams mounted onsaid shaft and adapted to contact with the respective valves, said camshaving low portions disposed in angular relation to each other andhaving high fPOIt tions provided with recesses, whereby either valve maybe held in unseatedjposition while the other valve remains 'inthe.Seated position.

2. A device of the character set forth, comprising a .cylindrical casingequipped with an outlet-spout and equipped with inlet-conduitscommunicatlng through the cylindrical wall of the casing, ball-valves insaid conduits projecting into the casing, a shaft extending into thecasing and equipped with a pair of cams correspondmg w1th said valvesand having peripheral portions adapted to contact directly with saidshaft.

3. A device of the character set forth, comprising a mixing-chamberequipped with an outlet-spout and equipped with a actuating planes ofthe respective valves, said cams having 'low portions substantially 180apart and high portions provided with recesses approximately 180 apart,for the purpose set forth.
